Embodiment Construction

[0023] figure 1 A disc separator 1 for separating material from a material mixture is shown. The disk separator 1 is preferably designed as an oil separator for separating oil from the blow-by gas. The disc separator 1 has a separating device 3 and an electric motor 5 for rotationally driving the separating device 3 . The separating device 3 is coupled in a rotationally fixed manner to an electric motor 5 . The electric machine 5 is designed as an external rotor electric machine and has a radially inner stator 9 with respect to the rotational axis 7 of the electric machine 5 and an outer rotor 11 .

[0024] The rotor 11 here has a substantially cylindrical outer surface 13 . Furthermore, the rotor 11 has an inner side 15 which cooperates with the stator 9 according to the functional principle of known electrical machines.

[0025] The separating device 3 is fastened to the rotor 11 and extends outwards in radial direction from the rotor 11 . The stator 9 at least partiall...

Abstract

The invention relates to a disc separator (1) for separating material from a material mixture, comprising a separating device (3) and an electric motor (5) for rotationally driving the separating device (3), wherein the separating The device (3) is non-rotatably coupled to the electric motor (5). It is proposed here that the electric machine (5) is designed as an external rotor electric machine and has a radially inner stator (9) and an outer rotor (11) with respect to the rotational axis (7) of the electric machine (5) ), wherein the separating device (3) is fastened to the rotor (11) and extends radially outwards from the rotor (11), and wherein the stator (9) is ) is arranged at least partially overlapping the separating device (3) as viewed in the axial direction.

Description

technical field [0001] The invention relates to a disc separator for separating material from a material mixture, having the features stated in the preamble of claim 1 . Background technique [0002] Disc separators are often used as oil separators, for example, to separate oil from blow-by gases which, in particular, pass from the combustion chamber of the internal combustion engine into the crankcase of the internal combustion engine. For operating such disc separators, in particular electric motors are used. Such disc separators typically also have a separating device with a plurality of rotatable disc elements. The drive and the separating device of a disk separator of the type mentioned at the outset require a relatively large installation space. Furthermore, the drive device and the disconnecting device each need to be mounted separately, resulting in corresponding costs. [0003] The prior art is for example document DE 10 2009 036 476 A1. It relates to a centrifu...
